Heart rate variability (HRV) and end tidal CO2 (ETCO2) in relation to treatment response have not been studied in Latino populations or in comorbid asthma and panic disorder (PD). An extension of previously published research, the current study explored psychophysiological variables as possible mediators of treatment response. Latino treatment completers (N = 32) in the Bronx with asthma-PD received either Cognitive-Behavioral Psychophysiological Therapy (CBPT) or Music Relaxation Therapy (MRT). CBPT included HRV-biofeedback (HRVB); in-the-moment heart rate data to help an individual learn to influence his/her own heart rate. The sample was primarily female (93.8%) and Puerto Rican (81.25%). Treatment groups did not differ on demographics, except for less education in CBPT. The Panic Disorder Severity Scale (PDSS) and Asthma Control Questionnaire (ACQ) assessed changes in symptoms. HRV and ETCO2 were measured at four of eight therapy sessions. Baseline ETCO2 and changes in HRV from first to last of psychophysiology sessions were investigated as mediators of change on ACQ and PDSS. Mixed model analyses indicated in the CPBT group, changes in both asthma control and PD severity were not mediated by changes in HRV. In the CBPT and MRT groups combined, changes in PD severity were not mediated by baseline ETCO2. These findings may be due to the brevity of HRVB in CBPT, multiple treatment components, ETCO2 not directly targeted, and/or unique physiological pathways in Latinos with asthma-PD.

对患有合并症哮喘和恐慌症的拉丁裔人的治疗反应的进一步探索:HRV和ETCO2作为治疗反应的潜在调节剂的简要报告。

尚未在拉丁裔人群或合并症哮喘和恐慌症(PD)中研究与治疗反应相关的心率变异性(HRV)和潮气末二氧化碳(ETCO2)。作为先前发表的研究的扩展,本研究探索了心理生理变量作为治疗反应的可能介导者。患有哮喘PD的布朗克斯区的拉丁裔治疗完成者(N = 32)接受了认知行为心理生理疗法(CBPT)或音乐放松疗法(MRT)。CBPT包括HRV生物反馈(HRVB);即时心率数据,可帮助个人学习影响自己的心率。样本主要是女性(93.8%)和波多黎各人(81.25%)。除了在CBPT中受过较少的教育外,治疗组的人口统计学没有差异。恐慌症严重程度量表(PDSS)和哮喘控制问卷(ACQ)评估症状的变化。在八个疗程中的四个疗程中测量了HRV和ETCO2。基线ETCO2和心理生理学过程中从头至尾的HRV变化作为ACQ和PDSS变化的调节剂进行了研究。CPBT组中指出的混合模型分析表明,哮喘控制和PD严重程度的改变均不受HRV改变的介导。在CBPT和MRT组合组中,PD严重程度的变化不受基线ETCO2介导。这些发现可能是由于CBPT中HRVB的简短,多种治疗成分,未直接靶向的ETCO2和/或拉丁裔哮喘PD患者的独特生理途径。研究了基线ETCO2和心理生理学过程中从头至尾的HRV变化,以此作为ACQ和PDSS改变的中介。CPBT组中指出的混合模型分析表明,哮喘控制和PD严重程度的改变均不受HRV改变的介导。在CBPT和MRT组合组中,PD严重程度的变化不受基线ETCO2介导。这些发现可能是由于CBPT中HRVB的简短,多种治疗成分,未直接靶向的ETCO2和/或拉丁裔哮喘PD患者的独特生理途径。研究了基线ETCO2和心理生理学过程中从头至尾的HRV变化,以此作为ACQ和PDSS变化的中介。CPBT组中指出的混合模型分析表明,哮喘控制和PD严重程度的改变均不受HRV改变的介导。在CBPT和MRT组合组中,PD严重程度的变化不受基线ETCO2介导。这些发现可能是由于CBPT中HRVB的简洁,多种治疗成分,未直接靶向的ETCO2和/或拉丁裔哮喘PD患者的独特生理途径。PD严重程度的变化不是由基线ETCO2介导的。这些发现可能是由于CBPT中HRVB的简洁,多种治疗成分,未直接靶向的ETCO2和/或拉丁裔哮喘PD患者的独特生理途径。PD严重程度的变化不是由基线ETCO2介导的。这些发现可能是由于CBPT中HRVB的简短,多种治疗成分,未直接靶向的ETCO2和/或拉丁裔哮喘PD患者的独特生理途径。
